From: Jarek Duda on 19 Nov 2009 13:14 You want to see charge as the more fundamental property - but maybe it's the other way... Look at the most fundamental, lightest particles - leptons: there is 'pure spin' particle (neutrino), but there is no pure charge one ... How to add charge to spin to create electron? Look at fig. 9 of 0910.2724

You need a current loop. -------------- Hi parrot you speak about spin while you dont know ***and dont mind*** how and why it is done you could as well say that it is done by witches on brooms the same with your Higgs Bosons Y.P --------------------------

I never said it was. I said you needed both in order to have a magnetic dipole moment.
